Touching the audio amplifier input at the moon

[bunalmis]

We hear hum sound If we touch the audio amplifier input.

What happen If we touch to amplifier input at the moon? What do we hear from headphone?

The hum you hear is a voltage induced in you from any adjacent power line. "f we touch to amplifier input at the moon?", you will need a very long cable, but moon = no power lines = no hum.
